Finally - an end to the "14-year-old boy with breasts" body shape! Scientists have isolated the hormone that, during body development, makes that oh-so-sexy hourglass shape that Marilyn Monroe had in spades. Depending on your position in the relationship, it might not be that great - women on the hormone look better, but they tend to be more self-confident, assertive, and sleep around more. Bad for husbands, good for boyfriends, eh? I suppose it's a worthy trade-off if it reduces the number of stick-thin, protruding-hipbone pseudo-beauties.
